It's like instead of clicking on a link you right click and select save target - that's how mirroring works - they just download the files. You're not rendering the page just downloading one file.
It's only when you open the downloaded file with a browser that it is rendered and possibly included javascript code is run, which can exploit some weakness in a specific browser.
Similarly to downloading malware - It doesn't do anything until you run it - but you can open the executable with a decompiler and look at what it does without actually running it.
